IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 206,443, dated July 30,1878 application filed April 17, 1878.

. To .all whom it may concern:

Y lowing isa full and exact description thereof, reference being had tothe accompanying drawings, making part of this specification- Figure lbeing a side view of the improved churn Fig. 2, an end view of the sameFig. 3, a side view, showing a modiiied const-ruction thereof, acting onthe same principle.

Like letters designate corresponding parts in all of the figures.

My invention consists in the combination,` wit-l1 a churn-body having areciprocating movement horizontally in a perfectly upright position, ofan oscillating weight or pendulum connected with the body of the churnto control the reciprocating motions thereof, substantially as hereinspecified.

- Y In the drawings, A represents a churn-body or cream-receptacle ofany suitable construction, but preferably oblong in the direction ot'its movement. It is provided with a truck, W, having friction-wheels aa, which run on tracks or ways b b of a stand, B. In this stand ismounted an oscillating weight or pendulum, C, hung on a rod, c, pivotedat d, or otherwise equivalently arranged. The upper end ot the rod cprojects a suitable distance above the pivot d, and is connected byaconnectingrod, D, with the churn-body, pivoted thereto at j', so thatthe oscillating movement of the pendulum will produce a correspondingreciprocating movement of the churn-body on its ways, or vice versa. Themovements of the churn-body and pendulum may be produced by a handle, E,secured to and projecting from one end of the pendulum-pivot l or themot-ion may be applied direct to the churnbody, or otherwise.

Instead of the particular construction above described, others embodyingthe same principle may be employed, as the one represented in Fig. 3.Here, instead of ways and friction-rollers for the churn-body to restand move on, it may rest on a table or support, G, which is mounted onoscillating standards H H, pivoted both to the table and to the base Iof the stand. The oscillation of these standards on the lower pivots, gg, produces an equivalent reciprocation of the churn-body always in anupright or horizontal position, but slightly varying in height indifferent parts of its reciprocating movement. This produces very littlefriction; and instead ot the connecting-rod between the pendulum-rod oand the churn-body, the upper end of this rod may be provided with afriction-roller, h,-

I `ig. 3, to play between parallel guides i t' on the bottom of thetable or of the churn-body, as represented. Other variations ot" theconstruction will readily be suggested.

By this movement of the churn-body, and the combination therewith ot'the oscillating weight or pendulum, I produce a very eii'ective motionof the churn, exactly calculated to produce the sudden dashes at theterminations of its vibrations best suited for operating the cream, andthis is effected with the least practicable friction or resistance, sothat churning with this apparatus is excecdinglyeasy and, since thechurn is constantly kept in an upright position, there is little or notendency to slop the crea-in over the ends of the churnbody, which is aserious objection to the tilting movement ot' other oscillating churns.

rlhe body A of the churn may be secured to the truck W by hooks l l on011e taking into hooks m m on the other, or otherwise.

That I claim as my invention, and desire to secure by Letters Patent,is-

The combination, with a churn-body, A, movable in a horizontal plane, ofan oscillating weight or pendulum, (l/,substantially as and for thepurposeherein specified.
